On a wider comment on the story as a whole, I think that one thing that some people are missing is that while yes, temples did fight oni, warlords, and other forces of evil, they also worked with them quite often. It was honestly more of a fifty/fifty split than anything. Which kind if shows the difference in cultures. In Western myth and religion, a church working with demons for any reason at all would be damned as heretics. In Eastern folklore and religion, such things are actually common, so long as the creature or force in question is not a threat to those under the temple's protection.
